An example of a diaphragm seal (in green) used to protect a pressure sensor.
A Diaphragm seal is a flexible membrane that seals and isolates an enclosure. The flexible nature of this seal allows pressure effects to cross the barrier but not the material being contained. Categories: Technology stubs | Seals (mechanical) ...
Common uses for diaphragm seals are to protect pressure sensors from the fluid whose pressure is being measured. A pressure sensor measures the pressure, typically of fluids, at a point in a fluid network. ...
Francesco Stelluti´s drawing of three bees were part of pope Urban VIII´s seal, and count as the first microscopic figure published (see Stephen Jay Gould, The Lying stones of Marrakech, 2000).
Most microscopes, however, have their own controllable light source that is focused through an optical device called a condenser with diaphragms and filters available to manage the quality and intensity of the light.
The whole of the optical assembly is attached to a rigid arm which in turn is attached to a robust U shaped foot to provide the necessary rigidity.
Connection sizes are usually larger (seal elements can also be provided with diaphragm extensions), and, because of the space requirement, they are usually installed at "radius tap" or "pipe tap" locations, as shown in Figure 2-3.
When chemical seals are used, it is important that the two connecting capillaries, as they are routed to the d/p cell, experience the same temperature and are kept shielded from sunlight.
The seals attach to the meter body immediately upstream and downstream of the restriction.
